Kanan has been married to her husband, whom she started dating in college, for five years. Living a mundane life, Kanan had some dissatisfaction with her lazy husband. One day, her husband reconnected with a classmate on SNS and hit it off, inviting other members to a reunion. The venue where the couple was invited turned out to be Nakata's home, the top floor of a high-end apartment with a pool… Nakata, who had been bullied by Kanan's husband in college, planned his revenge at this reunion… sending the couple straight to hell.
